Garrison swim is 7.30 to 8.30. A friend of mine came to try it out and was made most welcome. They have two lanes (1fast one slow) set aside in the garrison pool in the middle (I think lane 3/4) You can park opposite the entrance in North Camp at the end of (Queens Road is it?), go through to wet changing, get changed and go poolside. Haydn is the coach this week.
It's a brilliant pool!!! Tougher than a 25M and this seems to be added to by a 16 foot deep end.
Although I am but a lowly occasional member, I think it's OK to say the above!
Let us know how you get on, don't know if I can make it tomorrow or not.
